Interesting thread. Great comments. I have 14 years of code history under my belt personally from product development and marketing of hurricane impact windows and doors at a major manufacturer to now selling these same in the Florida panhandle for the past four years.
Florida state building code is based on a statistical analysis of how large of a hurricane can an area of the state expect to receive within a limited amount of time. Usually based on the life of a 30 year mortgage. Flooding is typically based on a 100 year timeline.
The code requirements for this area are based on no more than a category 3 storm hitting us and there is quite a pile of history to back that from ocean currents to how rare it is to get a storm to get past Cuba and then hook back into our area without heading to Galveston.
There has to be some guesswork involved and you have to draw a line somewhere. It is not reasonable to expect the entire coast of Florida to build to resist a Katrina or Andrew. The cost would be prohibitively high for the low risk of the event. Of course you are not prevented from building above code. Google "Fortified For Safer Living" and see what Alys has been aspiring to do.
Finding all the products that can meet these higher code levels creates challenges. Example from my industry would be windows built to withstand Miami hurricanes are not using insulated glass which I believe is a must in the panhandle, especially on a chilly 31 degree day like this morning. If you have single glass, you probably have water running down the insides this morning. Right?
